cryptsetup: default to no hash when keyfile is specified
For plain dm-crypt devices, the behavior of cryptsetup package is to ignore the hash algorithm when a key file is provided. It seems wrong to ignore a hash when it is explicitly specified, but we should default to no hash if the keyfile is specified. https://bugs.freedesktop.org/show_bug.cgi?id=52630
